BACKGROUND

During outages of power provided to cell sites by a commercial powerutility (e.g., via a utility grid), a telecommunications networkprovider may deploy generators to affected sites, in order to providesupplemental or temporary power to the sites during the outages. Thistemporary provision of power, via the deployed generators, enables thenetwork provider to maintain normal operations of the cell sites duringthe outages to the utility, which benefits customers of the networkprovider who utilize network provided services like voice, text, and/ordata communications via associated mobile devices (e.g., smart phones,tablets, laptops, and so on).

Typically, the network provider, via their emergency operations center(EOC), sends field technicians to the generator-powered cell sites toidentify or confirm sites where commercial power has been restored. Forexample, after a large outage (e.g., an outage affecting a large areawith many cell sites), the EOC may send out large numbers of techniciansover many work shifts to deploy generators and identify when sites havebeen restored. Thus, a generator at a cell site may operate for manyhours after power to the cell site has been restored and before atechnician arrives to determine power from the utility grid has beenrestored and to shut off the generator. Such an arrangement has variousdrawbacks, such as costs associated with wasted fuel at unneededgenerators, costs associated with technician time to travel and inspectcell sites, and so on.

DETAILED DESCRIPTION

Systems and methods are described herein for determining the restorationof power at a site, such as the restoration of commercial electricalpower to a cell site within a cellular telecommunications network. Thesystems and methods may be utilized to determine power is restored at acell site when a generator is currently or temporarily providing powerto the cell site (e.g., during a power outage on a utility grid thatprovided the power to the cell site).

For example, the systems and methods may include a first relay,connected to a power protection cabinet (PPC) of a cell site, whichsends a first signal representing a lost power state of the cell site,which indicates that the site has lost commercial electrical power. Thesystems and methods also may include a second relay, connected to thepower protection cabinet, which sends a second signal representing agenerator powered state of the site, in other words, indicating that agenerator is providing power to the site (e.g., during an outage ofpower from the commercial utility to the site). The systems and methodsdetermine that power is restored and available from a commercial utilityat a generator-powered cell site when detecting the second signalwithout the first signal (e.g., the first signal being cleared).

Thus, in some embodiments, the systems and methods may enable a networkprovider to receive immediate, automatic, notifications of powerrestorations at cell sites running on temporary generator power. Thisallows the network provider to efficiently control operations ofgenerators and other resources as well as effectively deploy field andservice technicians to cell sites during outages and restorations, amongother benefits.

The following description, for the purposes of explanation, numerousspecific details are set forth in order to provide a thoroughunderstanding of embodiments of the present technology. It will beapparent, however, that embodiments of the present technology may bepracticed without some of these specific details.

Examples of Power Restoration Indication Systems

As described herein, a power protection cabinet (PPC) of a cell site mayinclude various components or devices that provide power restorationindication messages or alarms when commercial (or, utility grid-based)electrical power is restored to the cell site after an outage or otherissue associated with providing power to the cell site.

FIG. 1 is a block diagram illustrating components of a power restorationindication system 100. A cell site 120 is connected to a utility grid110 (or, an optional generator 115) via a power protection cabinet 130,and receives commercial power from the utility grid 110. The cell site120 may be a cell site within a telecommunications network. For example,the cell site 120 may be a raw land site or other stand-alone site(e.g., stand-alone base station), a small cell site (e.g., a picocell,femtocell, microcell, and so on, and may include a self-support tower onwhich antennas are fixed and positioned to provide telecommunicationservices to mobile devices and other wireless devices within orproximate to the antennas.

The PPC 130 is positioned between the utility grid 110 and the cell site120, and includes power transfer devices configured to distribute powerto various locations within the cell site, devices configured to protectthe cell site from variations (e.g., surges) in power received from theutility grid 110, and so on. For example, the PPC 130 may include powertransfer pedestals, AC/generator power transfer points, mechanicalcircuit breakers, load centers, surge suppressors, and variouscompartments for mounting telecommunications (e.g., “telco”) and othercomponents.

The PPC 130 includes an over voltage protection (OVP) component 132,such as an OVP circuit or controller that protects from an overvoltagebeing applied to various devices of the cell site 120. The OVP component132 may connect or communicate to an alarm component 134, such as a SiteAlarm Unit (SAU) and/or external block of a Base Transceiver Station(BTS) Enclosure, in order to send signals associated with voltagefluctuations and other power distribution issues.

The power restoration indication system 100 may utilize such aconfiguration when integrating components, such as components of thepower restoration indication system 100, to monitor and identify whatdevices (e.g., the grid 110 and/or generator 115) are providing power tothe cell site 120 via the PPC 130.

The PPC 130 includes a first relay 150 that is connected to a commercialpower feed component 140 and the OVP 132, in order to monitor whetherpower is being provided to the cell site 120 (via the PPC 130) from theutility grid 110. The PPC 130 includes a second relay 155 that isconnected to a generator power feed component 145 and the OVP 132, inorder to monitor whether power is being provided to the cell site 120(via the PPC 130) from the generator 115. The relays 150, 155, may alsobe coupled to the alarm component 134, in order to send signals to thealarm component 134 based on whether power is being supplied into thePPC 130 via the commercial power feed 140 and/or the generator powerfeed 145.

The alarm component 134, which is described in more detail herein, isconfigured to send and transmit various alarm messages associated withthe state of the PPC 130, the state of the OVP component 132, and/or thestate of the relays 150, 155. These alarm messages, when received invarious combinations, may indicate certain states of the PPC 130 andassociated cell site 120, such as overvoltage states, commercial-basedpower states, generator-based power states, power outage states, powerrestoration states, and so on.

The power restoration indication system 100 may be included in PPCs thatare newly deployed to a cell site and/or installed (e.g., retrofit) intoexisting PPCs. An example installation is as follows.

Although various different cell sites 120 and site locations may utilizethe power restoration indication system 100, certain cell sites maybenefit specifically from a mechanism that provides immediatenotifications of power being restored to sites running with generators.For example, such sites may be a raw land site with a self-supporttower, may include a certain style/configuration/sized PPC 130 (e.g.,sites with 2G & 3G/2000 series & 3000 series PPCs) and/or certaingenerator plug/connector configurations. Also, the site locations mayinclude locations where commercial power is slow to be restored (e.g.,rural or isolated locations), planned site builds and sites scheduledfor modernization (e.g., upgrades to the PPCs), sites where power isoften out due to storms or other issues, and so on.

Once a site is selected, installation of components configured toprovide power restoration indications may include some or all of thefollowing actions:

The installation of two RIB (relay-in-a-box) relays (e.g., relays 150,155) in the telco section (power distribution portion) of the PPC 130;

The installation of two 5 A in-line fuses on the commercial power feed140 using live taps, so power will not be interrupted to feed the RIBrelay 150 with 240V;

The installation of two 5 A in-line fuses on the generator power feed145 using live taps, so power will not be interrupted to feed the RIBrelay 155 with 240V;

The installation of a Cat 5 cable (or, use existing one already in thePPC 13), to run contacts from the relays to a BTS external alarm block(e.g., alarm component 134), using 1 pair of the Cat 5 cable for a“generator power alarm,” and using another pair of the Cat 5 cable for a“no commercial power available” alarm;

The connection of the Cat 5 cable to the external alarm block in the BTS(ensuring that the patch cord is connected to, and terminates at, thecorrect ports on an associated SAU module, and that a connection betweenthe SAU and a fan control unit is verified). Of course, otherinstallation configurations are possible.

Thus, the relays 150, 155, being installed within a power distributionportion of the PPC 120 (e.g., connected to the OVP 132), may providesignals associated with the presence or absence of power within acommercial power feed 140 and/or generator power feed 145. The alarmcomponent 134 may utilize such signals to generate alarm messagesassociated with various powered states of the PPC 130 and/or cell site120, which indicate whether power has been restored to the cell site120.

FIG. 2 is a flow diagram illustrating a method 200 for determining arestoration of commercial power to a site, such as a cell site. Inoperation 210, the system receives a first alarm message from the alarmcomponent 134 at the power protection cabinet 130 of the cell site 120that indicates an outage of power at the cell site 120. The first alarmmessage may be a commercial power fail alarm that indicates a lost powerstate of the cell site 120. For example, the alarm component 134 mayreceive a signal from the relay 150 connected to the power protectioncabinet 130 of the cell site 120, where the relay 150 sends a signalrepresenting a lost power state of the cell site 120.

In operation 220, the system receives a second alarm message from thealarm component 134 that indicates that the generator 115 is providingpower to the cell site 120. The second alarm message may be a “siterunning on generator” alarm, which indicates that the cell site 120 isrunning on power provided by the generator 115 during a generatorsupplied power state of the cell site 120. For example, the alarmcomponent 134 may receive a signal from the relay 155 connected to thepower protection cabinet 130 of the cell site 120, where the relay 155sends a signal representing a generator supplied power state of the cellsite 120 that is based on the generator 115 providing power to the cellsite 120 during the outage of power from the commercial utility 110 tothe cell site 120.

The system may receive the message at or within the PPC 130, or at otherlocations remote from the PPC 130, such as at a network operationscontrol center (NOCC), an emergency operations controller (EOC), orother locations associated with the management or control of thewireless communications network.

In operation 230, the system determines that power has been restored atthe cell site based on a clearance of the first alarm message thatindicates the outage of power at the cell site has cleared, and based ona presence of the second alarm message that indicates the generator isproviding power to the cell site.

In some embodiments, the system may automatically send a restorationnotification to the NOCC, the EOC, a network Switch, or other controldevices or systems of the telecommunications network, upon determiningpower has been restored at a site where a generator is currentlyrunning. The various control centers may then deploy field techniciansin response to the restoration notifications.

Thus, in some embodiments, the restoration indication system may utilizerelays 150, 155 connected to various power distribution components(e.g., OVP 132) of the PPC 130 in order to identify current power states(e.g., a normal, or grid-supplied power state and/or a temporary, orgenerator-supplied power state) for the cell site 120. The system mayalso utilize various alarm components (e.g., alarm 134) in order togenerate and transmit alarm messages indicative of power being restoredto the cell site 120.

For example, FIGS. 3A-3E illustrate user interfaces that depict theprovisioning and selecting of alarm messages utilized by the powerrestoration indication system.

FIG. 3A depicts a user interface 300 of a management system associatedwith the cell site 120, such as a system that manages the control,provisioning, customization, and so on, of network components andelements for a wireless telecommunications network (e.g., the ElementManager by Ericsson®). The user interface 300 includes a list ofequipment 310 and other devices to be configured via the managementsystem, including an entry 315 for “external alarms” of a managedelement (the cell site 120, or PPC 130).

Once the “external alarms” entry 315 is selected, the management system,as depicted in user interface 320 of FIG. 3B, expands the entry 315 toinclude multiple entries 325 associated with alarm ports for the SiteAlarm Unit (SAU) of the cell site 120.

Upon selection of an alarm port (e.g. “alarmportID”=1), the system, asdepicted in FIG. 3C), provides a user interface 330 of user-configurabledisplay elements via which a user (e.g., site engineer) may configurethe alarm messages described herein. The user interface 330 may displayvarious parameters to be set by the user via a MO (Managed Object)Properties tab. For example, the user may make the following selectionswhen provisioning the “commercial power fail” alarm message:

Define an alarmslogan parameter as a “Comm Power Fail”;

Set normallyOpen parameter to true;

Set perceivedSeverity parameter to Critical[2];

Set probablecause parameter to Remote_Alarm_Indication; and so on.

Similarly, as depicted in FIG. 3D, the user may make parameterselections when provisioning the “site running on generator alarm”message via user interface 340, as follows:

Define an alarmslogan parameter as a “Running on Generator”;

Set normallyOpen parameter to true;

Set perceivedSeverity parameter to Critical[2];

Set probablecause parameter to Remote_Alarm_Indication; and so on.

Once parameters for alarm message have been provisioned, the user, viauser interface 350 depicted in FIG. 3E, creates a configuration version,with associated properties, in order to maintain the newly created alarmmessages in the system.

Thus, the management system, via various provided user interfaces,enables users to create and provision the different alarm messages thatindicate the restoration of power to a site running on a generator.

Therefore, the systems and methods enable power protection cabinets 130at cell sites 120 to immediately notify various network managementcenters or controllers when power has been restored to those cell sites120 that have been running on generators 115 after outages to commercialpower grids 110 that normally supply power to the cell sites 120.

As described herein, the PPC 130 may provide or facilitate suchimmediate notifications when configured with the following components:

a first relay, connected to a power protection cabinet of the wirelesstelecommunications site, wherein the first relay is configured to send afirst signal representing a lost power state of the wirelesstelecommunications site, and wherein the power protection cabinetincludes power transfer devices configured to protect the wirelesstelecommunications site,

a second relay, connected to the power protection cabinet, wherein thesecond relay is configured to send a second signal representing agenerator supplied power state of the wireless telecommunications site,and wherein the second signal is based on the backup generator providingpower to the wireless telecommunications site during an outage of powerfrom the commercial utility to the wireless telecommunications site, and

a processor or microcontroller programmed to determine that power isagain available from the commercial utility at the wirelesstelecommunications site after the lost power state, wherein theprocessor or microcontroller determines that power is again availablefrom the commercial utility upon first detecting an alarm associatedwith the second signal and then detecting a clearing of an associatedwith the first signal.
